DM330022-1

DM330022-1 is a DSPICDEM™ MCSM development board targeted to control both unipolar and bipolar stepper motors in open-loop or closed-loop (current control) mode. The hardware is designed in such a way that no H/W changes are necessary for 8, 6 or 4-wire stepper motors in either bipolar or unipolar configurations. S/W to run motors in open-loop or closed-loop with full or variable micro-stepping is provided. A GUI for controlling step commands, motor parameter input and operation modes is included. This flexible and cost-effective board can be configured in different ways for use with Microchip’s specialized dsPIC33 motor control DSCs. This board offers a mounting option to connect either 28-pin SOIC or generic 100-pin PIM. A dsPIC33CK64MP105 external op-amp MC PIM (MA330050-1) is included that features 4-ch, high-speed PWM with complementary mode O/P, programmable ADC trigger on PWM reload cycle, digital dead time control, internal shoot-through protection and hardware fault shutdown.
